The default reporting time period is the first day of the current month until the last complete day of data, yesterday. The exception to this rule is EOM (End of Month) days. If run within 5 days of of the end of the month (ie, the 1-5 of the next month), then the reporting interval is the previous complete month.

This setting allows specification of how many days -back are used when calculating the month to report. To run a report for the previous month when the current day is greater than 5, set -back to a value of todays day plus one.

If the -back option doesn't provide the exact date range you want, you can optional specify a -start and -end day for the report. This would be useful if you were reporting on a basis other than monthly.

Generates an uplink report that shows how much traffic each ISP uplink port is utilizing. We run this report weekly and it gives our operations team and executives a high level overview of our network traffic. It also gives us handy reference points to compare and validate the usage our ISPs bill us for. An example is included.
